The relationship between lysate protein concentration from untreated and TNF-α and IL-1β treated HeLa cells and the absorbance at 450 nm using PathScan® Total NF-κB p65 Sandwich ELISA Antibody Pair #7836 is shown. HeLa cells were treated with TNF-α and IL-1β for 5 minutes at 37ºC and then lysed.Learn more about how we get our images
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
1X Cell Lysis Buffer: 10X Cell Lysis Buffer (#9803): To prepare 10 ml of 1X Cell Lysis Buffer, add 1 ml of 10X Cell Lysis Buffer to 9 ml of dH2O, mix. Buffer can be stored at 4°C for short-term use (1–2 weeks).

CST's PathScan® Total NF-κB p65 Sandwich ELISA Antibody Pair is offered as an economical alternative to our PathScan® Total NF-κB p65 Sandwich ELISA Kit #7174. Capture and Detection antibodies (100X stocks) and HRP-conjugated secondary antibody (1000X stock) are supplied. Sufficient reagents are supplied for 4 x 96 well ELISAs. The NF-κB p65 Capture Antibody is coated in PBS overnight in a 96 well microplate. After blocking, cell lysates are added followed by a NF-κB p65 Detection Antibody and anti-Mouse IgG, HRP conjugated antibody. HRP substrate, TMB, is added for color development. The magnitude of the absorbance for this developed color is proportional to the quantity of total NF-κB p65 protein.
Antibodies in kit are custom formulations specific to kit.
Capture and detection antibodies are stored at 4°C. HRP-linked secondary reagent is stored at -20°C.
For Antibody Pair specificity and sensitivity, please refer to the corresponding PathScan® Sandwich ELISA Kit. Note: This antibody pair detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.
Transcription factors of the nuclear factor κB (NF-κB)/Rel family play a pivotal role in inflammatory and immune responses (1,2). There are five family members in mammals: RelA, c-Rel, RelB, NF-κB1 (p105/p50), and NF-κB2 (p100/p52). Both p105 and p100 are proteolytically processed by the proteasome to produce p50 and p52, respectively. Rel proteins bind p50 and p52 to form dimeric complexes that bind DNA and regulate transcription. In unstimulated cells, NF-κB is sequestered in the cytoplasm by IκB inhibitory proteins (3-5). NF-κB-activating agents can induce the phosphorylation of IκB proteins, targeting them for rapid degradation through the ubiquitin-proteasome pathway and releasing NF-κB to enter the nucleus where it regulates gene expression (6-8). NIK and IKKα (IKK1) regulate the phosphorylation and processing of NF-κB2 (p100) to produce p52, which translocates to the nucleus (9-11).
